3 Ciaims. (Cl. 189-42) This invention relates to improvements in solid metal windows, and particularly the windows of the general type shown in Campbell Patent No. 1,549,711 of April 11, 1925. Broadly speakins.

a windows of this type are characterized by the fact that the lambs of the window have openings through the inner lamb walls with a parting strip forming a part of the inner lamb wall between these openings and separate enlarged chambers 10 back of the openings. and the sashes have plates adapted to extend throughthe openings.

In windows pf this type the seal against the weather has heretofore been made at the joint between the parting strip-and the sashes on each 18 side of it. It must be borne in mind that the enlarged chamber into which the upper (outer) sash enters will be opened to the atmosphere belowthissash andsowillreceive coldair andin the same way the chamber into which the inner l sash enters will be open to the room above the sash and therefore be full of warm air. Accordingly, it is important that there must be a seal to prevent warm .air from leaking out between the lower sash and the parting strip or to pre- 15 vent cold air from leaking in between the upper sash and the parting strip.

Because of this situation and to prevent rattling, windows of this type have heretofore been adjusted so as to have a very slight clearance be- 30 tween the inner lamb wall members and the plates of the sash. This, however, has created diiliculty in that when the windows were painted it would tend to cause the sashes to bind, and if the jamb members were originally adjusted with 35 extra clearance. then the windows would rattle.

, In accordance with the present invention, I am able to overcome these defects by providing a groove or channel inside of the jamb and substantially back of the inner jamb wall which will re- 40 ceive the edge sash plate and hold it firmly enough so that it will not rattle very much in this inner channel, and at the same time hold it so that it will not contact with either of the inner jamb wall members in the plane of the inner 45 Jamb wall. The actual sealing between the parting strip and the sash can be accomplished by the use of sealing members of the general type described in Campbell Patent No. 1,673,393 of June 12, 1928.

60 By this construction, the inner jamb wall members serve only as cover plates;' they neither control the lateral movement of the sash nor do they guide it in its up and down movement, nor do they serve as a primary means of keeping out the so weather, but all of these functions are care of within the enlarged chambers. Since it is not necessary to have the paint go inside the enlarged chambers, and since all the functional relations of the window take place within these chambers, the application of paint will not interfere with the window functions.

I have also found that a window embodying my invention can be used to great advantage with springs substituted for counterweights. This permits me 'to make the jamb rather small and to make mullioned windows with very narrow mullions.

When window weights are used, it ordinarily is not advantageous to ship the window frames with the weights in place, as they tend to move -1 in the frames and cause damage. This difliculty is done away with by the use of the springs. Also due to the fact that the various functionalrelations between the sashes and the jambs take place within the jamb chambers, I can use either spring metal or metal of a relatively thin gauge for the various contacting parts and this permits ease of adjustment so that the windows can be shipped from the factory substantially ready for use (after glazing) and extensive field adjust- 26 ments are eliminated.

This invention can readily be understood by reference to the accompanying drawing, in which Fig. 1 is a sectional view through the head and sill of a window and through the sashes showing the inner face of the jamb wall; Fig. 2 is a transverse section through the upper sash; Fig. 3 is a section corresponding to the sections shown in Fig. 2 but showing a mullioned connection, and Fig. 4 is a modified construction corresponding to that shown in Fig. 2.

Referring to Figs. 1 to 3, the numeral Ill designates the main jamb member which forms a portion of the inner lamb wall as indicated at I! and is bent as indicated at ll to form one-half of an inner channel or groove. The parting strip I6 is formed with two legs l8 which are extended to form portions 2i! that lie parallel with member I0 and to form the groove members 22 and 24. The balance of the inner jamb wall is formed by the member 26 which is bent backwardly at 28 and then runs parallel with member I 0 ex-. cept that it has a double bend as indicated at 30 to form a channel or groove member.

It will be noted that in this construction, each of the members which forms a portion of one of the inner grooves or channels is integral with the portion of the inner jamb wall lying directly outside of it and each of these groove or chanbe] members is so shaped that the sash plates 56 with the parts forming the inner jamb walls,

sealing means is supplied to make a seal between.

entering the grooves or channels cannot contact with the inner jamb wall members.

As will be obvious from Fig. 2, the parting strip l6 and member 26 are both held clamped against member. ill by screws 32. It is to be understood that the openings into which these screws extend are somewhat larger than the screws so as to permit some movement and adjustment of the parts. Thus by loosening the screws, member I6 .can be brought into correct position relative to portion I! of member l0 and then member 28 can be brought into correct position relative to the parting strip IS. The screws are then tightened. The upper sash is designated by the numeral 34 and is provided with sash plates 36 and in the same way the lower sash 38 is provided with sash plates 40. Since the sash'constructiomforms no part of the invention claimed in this case, the construction of the sashes is not described indetail.

Since the groove members within the jambs are so arranged that the sash plates cannot contact the sash plates and the parting strip. In this case such sealing means consists of a member '42 bent around each of the sash plates and bearing against the back of the inner jamb wall portion of the parting strip. These members 42 move vertically with the sashes but are so mounted on the sashes that longitudinal movement of the sash within the sealing members is permitted all as is more fully explained in the said Campbell Patent No. 1,673,393.

The numeral 44 designates two coil spring housings (shown in Fig. 1) mounted in the'head of the sash frame. From each of these members extends a metal tape attached to one of the sash plates as indicated at 46 in Fig. 2.

In the mullion construction shown in Fig. 3, two members 48 and 50 which may be attached together in any convenient way, as by welding, take the place of two members Ill arranged back to back. The rest of the parts corresponds directly to a double set of the parts already described in connection with Fig. 2. This makes a very narrow and simple mullion.

In Fig. 4 I show a channel arrangement functionally similar to that already described adapted for use with a standard window construction employing window weights. In this case the chain pocket member 52 forms a portion of the inner jamb wall and carries the parting strip 54. The balance of the inner jamb wall is formed by the member 56 which connects to the jamb member forming the weight box in the manner well understood in the art; for example, as shown in Campbell Patent No. 1,549,711.

In this case, the inner groove members are not made integral with the underside groove members but are formed by two separate pieces II and 04 each oi which runs the full height of the lamb and is bent to form an inside groove as clearly shown in Fig. 4. These members It and I are screwed to member I! and are so adjusted that the sash plates entering their grooves will not contact with the members 52, 54 and I. As before, the separate sealing members are supplied consisting of the members 82 hooked over the legs of the parting strip 54 and the members 84 carried by the sash plates. These follow directly the construction shown in Fig. 1 oi? Campbell Patent ,No. 1,673,393.
